Description
The inclusive γ cross section in K+p interactions at 70 GeV/c shows an excess of (4.5+-0.9) mb over the contributions arising from hadron decays. The excess consists of soft γ's with -0.001<x<0.008 and psub(T)<0.06 GeV/c. The shape of this soft γ spectrum is consistent with that expected from QED inner bremsstrahlung, but the measured total cross section exceeds the QED expectation, indicating the presence source(s) of soft photons.
